Porsche V10 engine

The Porsche V10 engine is a naturally-aspirated, V-10, internal combustion piston engine, designed and developed by Porsche, originally as a concept design for Formula One motor racing in the 1990s, and later Le Mans racing, but eventually used in the Porsche Carrera GT sports car; between 2003 and 2007. The engine is derived from the unsuccessful Porsche 3512 3.5-liter 80° V12 engine, used in the early 1990s.^{[3][4][5][6][7][8][9][10][11][12][13]}

Background

A V10 replacement for the 3512 was in development at the time of Porsche's withdrawal from Formula One. This engine would not be completed until several years later, when it was modified for use in the stillborn Porsche LMP project in 2000. The engine design eventually was re-used when a further variant was chosen as the powerplant of the Porsche Carrera GT supercar.
